Note:

Stresses greater than those listed under MAXIMUM

RATINGS may cause permanent damage to the device. This

is a stress rating only and functional operation of the device

at these or any other conditions above those indicated in the

operational sections of this specification is not implied. Ex-

posure to absolute maximum rating conditions for extended

periods may affect reliability.

Notes:

1. This parameter is guaranteed but not tested on Propagation Delays.

2. The bus switch contributes no propagational delay other than the RC delay of the On-Resistance of the switch and the load capacitance. The

time constant for the switch alone is of the order of 0.25ns for 50pF load. Since this time constant is much smaller than the rise/fall times of

typical driving signals, it adds very little propagational delay to the system. Propagational delay of the bus switch when used in a system is

determined by the driving circuit on the driving side of the switch and its interaction with the load on the driven side.

3. See test circuit and waveforms.

Note:

1. Typical values are shown at VCC = 3.3V, +25°C ambient and maximum loading.
